In their own words
Caido
Caido is a web security auditing toolkit for scaling manual testing through AI and teamwork. Its proxy intercepts and monitors HTTP and WebSocket traffic, with history for intercepted traffic and WebSocket messages. HTTPQL filtering lets users search requests and responses. Node-based workflows support ad-hoc automation, and automated attacks can use custom payloads and placeholders. Users can connect existing LLM providers, including Anthropic, Google, OpenAI, and providers available through OpenRouter. AI agents can access Caido programmatically through its Client SDK. Community plugins and custom extensions are supported; the Basic plan allows three plugins. Basic is free forever and includes two projects, seven workflows, five filter presets, and one pipeline session at a time. The pricing note lists paid access from $20/user/mo, while the opened pricing page did not display prices for Individual, Team, or Enterprise. Caido lists Linux, macOS, Windows, web, API, and self-hosted platforms, and presents the product for pentesters, security engineers, and bug bounty hunters.
Kali Linux
Kali Linux is a Debian-based distribution for advanced penetration testing and security auditing. It includes tools and configurations for computer forensics, reverse engineering, vulnerability detection, and other information security work. Its listed tools include Aircrack-ng, Burp Suite, Hydra, John the Ripper, Metasploit Framework, Nmap, sqlmap, and Wireshark. Kali is intended for experienced penetration testers and security specialists; its documentation assumes Linux familiarity. It supports bare-metal installs, virtual machines, cloud, containers, ARM devices, USB or DVD live environments, and Windows Subsystem for Linux. A Live USB can run without changing the host operating system, and persistence volumes can be encrypted. Users can build custom ISO images with metapackages and live-build. Network services are disabled by default, Bluetooth is blocklisted, and packages and repositories are signed. Kali is free of charge, though its non-free section includes some tools that are not open source. It follows a rolling release model, with fresh official point-release images generated quarterly. Kali NetHunter is a free and open-source Android penetration testing platform with a Kali container, desktop experience, app, and app store.
